Differential diagnosis

Male of Spinirta yintiaoling Wang, Lu & Z.S. Zhang sp. nov. resembles S. hongyui sp. nov. in having the similar quadrangular embolar apophysis ( Figs 12 View Fig , 13B–D View Fig vs Figs 4A–B View Fig , 5F–G View Fig ) but can be distinguished by the ventral tibial apophysis tip rounded in S. yintiaoling ( Figs 12 View Fig , 13B–D View Fig ), whereas somewhat triangular in S. hongyui ( Figs 4A–B View Fig , 5E–G View Fig ); retolateral tibial apophysis tip rounded in ventral view in S. yintiaoling ( Figs 12 View Fig , 13C–D View Fig ), whereas wavy in S. hongyui ( Figs 4A–B View Fig , 5F–G View Fig ).

Etymology
